After WWI, the Royal Families realised that the International Treaty initiated by Tsar Alexander II of Russia needed some amendments to protect the Wealth of the World.
In 1920 the Royal Families of the World convened in London to agree the restructuring proposed by Emperor Hirohito, who volunteered to design a new plan.
The proposals by Emperor Hirohito were unanimously approved by the Royal Families of the World.
The Treaty was executed in 1920 although this was not actually concluded until early 1921.
In 1929 some amendments to the London Treaty 1920 were approved.
